Trends in the development of hybrid vehicles
Ďurica, Matej ; Tobiáš, Martin (referee) ; Štětina, Josef (advisor)
This bachelor thesis is dedicated to make brief research in the hybrid automotive department, focused on the last ten years of development. The first part describes the categories of hybrid vehicles with an emphasis on the development of accumulators and related technology. An important part is the advantages and disadvantages of systems and drives. The second part deals with the future of hybrid drives, applications mainly in heavy industry, and the possibilities of changing "heavy" fossil fuels with "greener" alternatives. At the end of the work is the evaluation of the impact of the COVID crisis on the automotive industry.

Determination of Acoustic Properties of Sound-Absorbing Materials
Ďurica, Matej ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This diploma thesis is focused on experimental determination of acoustic absorption of four different material samples. The aims of the work include: research on the given issue, determination of the procedure for the performance of a technical experiment and modification of the measuring device for the determination of acoustic absorption. The performed experiments were evaluated and the results of the sound absorption coefficient were compared with the values given by the manufacturer. Sensitivity analyzes of the experiments were performed.

Building and using smaller computer networks
Ďurica, Matej ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
In these days, the widespread creation of home networks, due to the continuous development of computer technology for personal use. These networks are formed, for example, with the aim of facilitating access to information, ease of communication between people and control of various devices in the home. Their development is influenced by trends in information communication technologies in the market. This bachelor thesis is fully focused on the practical implementation of the proposal for extension of the original smaller home network using the new network elements (wireless routers, switches, network printers, NAS server, device for live monitoring of security cameras) and rendering certain network services (DLNA, print server, VPN, iTunes server, live monitoring of security cameras). A given network was tested with respect to performance network and its response, coverage of Wi-Fi signal, testing remote access, power consumption, read and writes speed of the NAS server.
